Products Description
APTSS-22 Differential Pressure Sensor 19mm: Built for Precision and Reliability
The APTSS-22 Differential Pressure Sensor is a robust, media-isolated sensor designed for industrial applications requiring high accuracy and reliability. Encased in a sturdy Stainless Steel body, the APTSS-22 delivers safe and efficient differential pressure measurement demanding environments. Because it is engineered with precision and quality, it provides exceptional stability, reliability, and replaceability, making it a versatile choice for various industrial uses.
Precision in Pressure Measurement
At the heart of the APTSS-22 is its advanced pressure measurement mechanism. The sensor transmits pressure through a diaphragm and measures it with silicon oil, ensuring precise and consistent readings. Consequently, this innovative design delivers accurate results across a wide range of media, including air, gas, and most non-corrosive substances. Furthermore, the APTSS-22 offers an impressively fast response time of 1 ms, making it ideal for applications where rapid data acquisition is critical.
Robust Industrial Design of the APTSS-22 Differential Pressure Sensor
The APTSS-22 features a housing crafted from durable Stainless Steel, which ensures resistance to environmental factors and compatibility with various industrial applications. Additionally, the wetted parts, also made from Stainless Steel, provide long-lasting durability and performance. Since the sensor includes a dual-diaphragm design, it allows pressure to be applied and measured on both sides. As a result, this enhances its adaptability and precision in differential pressure monitoring.
Exceptional Stability and Reliability
Because the APTSS-22 is designed with long-term performance in mind, it offers outstanding stability, rated at ±0.5% FS/Year. This high level of stability ensures that your pressure readings remain reliable and accurate over extended periods. Therefore, the sensor reduces the need for frequent recalibration and maintenance, saving time and costs in the long run.
